This site is a portage. This typically means there either is no road access to this location or that the site is not recommended as a launching site for some other reason. The portage may be around a dam, whitewater, or some other obstruction.

Description & Overview:

While there is road access to this site it is signed "private property" and there is much better parking and river access at Plummer's Landing, a mile downriver. However, if you are paddling down the river from above Riverdale Mills you will have to portage around the dam at Riverdale Mills. If possible, take out on the left side of the river before the footbridge and carry up to the dirt track the runs parallel to the river. From there look for a path leading down to the river. There is lots of poison ivy in the area so be careful what you touch. The path should get you to a gravel bar where you can put into the river but this is a strenuous portage.

If you can't take out on river left you'll have to take out in front of the mill and carry over the footbridge. Ignore the sign pointing the wrong way to a non-existent portage somewhere to the west.

Either way, this is a strenuous portage.

Below the dam the river is a mix of flatwater and quickwater. The riverbanks below Riverdale are largely wooded and rural for many miles, with only very occasional houses and buildings visible from the river.

NOTE: There are ongoing issues with pollution in the Blackstone River. Great strides have been made in cleaning up the river relative to where it was a generation or two ago but under some conditions the water may still have a noticeable odor.

This site provides access to the following water bodies in the Blackstone River watershed: Blackstone River.

This view shows the lower part of the Riverdale Mills dam and a bit of the river below the dam. The put-in is on the far shore, at the right edge of the picture. The gravel bar in the middle of the picture has a steep bank behind it. Stay on top of this bank and walk past this gravel bar to the low bar on the right, where there is better access. The footbridge over the river is above the upper dam and not in this picture. The foam on the river is from the water falling over the large dam just upstream.
